Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a decorative sheet in which a pattern is three-dimensionally expressed and further changed.

[0002]

2. Description of the Related Art The inventors have proposed a decorative sheet whose pattern changes depending on the viewing angle (Japanese Patent No. 276186).
No. 1, Japanese Patent No. 3131771).

This decorative sheet comprises a front surface side sheet and a patterned rear surface side transparent sheet. By changing the pattern arrangement interval of the rear surface side transparent sheet,
The pattern appears to rise and fall or to sink. As a result, a three-dimensional decoration effect can be exhibited on the table cover, shower curtain, window decoration sheet, bag, and the like.

By the way, there is a demand to further change the three-dimensionally expressed pattern.

[0005]

Therefore, the present invention is intended to provide a decorative sheet in which a three-dimensionally expressed pattern changes.

[0006]

In order to solve the above problems, the present invention takes the following technical means. The decorative sheet of the present invention is characterized in that a pattern is three-dimensionally expressed by a lens portion having a plurality of convex lens-shaped projections and a pattern portion having a pattern, and the plurality of convex lens-shaped projections are provided in a different manner.

In this decorative sheet, a pattern is three-dimensionally expressed by a lens portion having a plurality of convex lens-like protrusions and a pattern portion having a pattern. However, the plurality of convex lens-like protrusions are provided by changing the three-dimensional shape. The pattern appears through a plurality of convex lens-like protrusions that are provided by changing the pattern.

The plurality of convex lens-like protrusions can be provided, for example, by changing the arrangement interval. In addition, the convex lens-shaped protrusion may have a hemispherical shape, an elliptic spherical shape, or a conical shape such as a cone shape. The lens portion and the pattern portion may be integrally formed or may be separately formed. The lens portion and the pattern portion may be a light-transmissive sheet body. The decorative sheet may have a single-layer structure or a laminated structure. An illumination display mechanism may be provided so that a pattern is three-dimensionally expressed with respect to the displayed contents displayed.

According to this structure, the pattern is three-dimensionally expressed with respect to the display content (illumination display portion) displayed by the illumination display mechanism, and further three-dimensionally by the plurality of convex lens-shaped projections that are provided in a changed manner. The pattern will change.

Examples of the illumination display mechanism include an LED display function, an electric display function such as a liquid crystal display, and a printed matter such as a negative, positive or pattern.

The portion for providing the display contents (illumination display portion) may be either the front or back of the decorative sheet or may be the middle thereof. The interval between the plurality of convex lens-shaped protrusions may be changed stepwise or steplessly.

According to this structure, the pattern and the displayed contents are three-dimensionally visible and stepwise (stepwise gradation).
Or, it changes steplessly (smooth gradation).
The interval of the array of the convex lens-like protrusions can be reduced stepwise or steplessly and can be increased, or both reduction and expansion can be performed.
It should be noted that the stepless change has a moving-image effect even in a still pattern, and in display contents having a moving image property, a more moving-image effect can be obtained by a synergistic effect of both. The interval of the array of the plurality of convex lens-like protrusions may be a stepwise or steplessly biased body.

According to this structure, the pattern and display contents are three-dimensionally visually recognized and are expressed stepwise (stepwise gradation) or stepless (smooth gradation) in one direction. It should be noted that the stepless change has a moving-image effect even in a still pattern, and in display contents having a moving image property, a more moving-image effect can be obtained by a synergistic effect of both. The interval of the array of the plurality of convex lens-like protrusions may be partially changed.

With such a structure, a different three-dimensional effect is produced on the part which has not been changed due to a partial change in the pattern and display contents, so that a more prominent three-dimensional decoration effect can be obtained. Further, since it is possible to obtain a moving image effect due to this effect, it is possible to obtain a more moving image effect in the display content having moving image property. The intervals between the plurality of convex lens-shaped protrusions may be partially biased.

With such a structure, the pattern and the display content are partially biased, and different stereoscopic effects are produced in the non-biased portions, so that a more prominent stereoscopic decorative effect is obtained. . Further, since it is possible to obtain a moving image effect due to this effect, it is possible to obtain a more moving image effect in the display content having moving image property. The interval of the array of the plurality of convex lens-like protrusions may be a combination of each of the above items 1 to 3. In this way, by changing the combination, the pattern and the display content are expressed with more various three-dimensional decoration. The intervals between the arrays of the plurality of convex lens-shaped protrusions may be biased so that they are substantially constant.

With this structure, the decorative sheet has about 9
The ups and downs of the pattern are reversed every time it is rotated 0 degree. This was a very interesting phenomenon.

Such an excellent three-dimensional decoration effect can be applied to various products to increase their added value.

Further, when the display contents are set to move in the horizontal direction, the display contents are expressed in a three-dimensional manner by the synergistic effect of the animation property of the display contents and the animation property due to the stepwise gradation effect of the moire pattern. can do.

This electric display can be used as a name of a station to stop next or an illumination display board of a destination in a train. Here, in contrast to the three-dimensional moire pattern, a mode in which the name of the station to stop next rises from the state of being relatively depressed and then sinks again can be adopted. It can also be used as a display board of a digital clock or a display board of a pachi-slot machine. (Third Embodiment) Next, a third embodiment will be described focusing on differences from the second embodiment.

The lens portion of this decorative sheet (electrically decorated display body) is provided with a plurality of convex lens-like projections provided by continuously changing the arrangement intervals in the horizontal direction. That is, the interval between the convex lens-like protrusions is increased or decreased by the smooth gradation. Therefore, the moire pattern is three-dimensionally expressed while exhibiting a smooth gradation effect by the interaction between the convex lens-like protrusions that are provided by being changed and the pattern.

Further, when the backlight of the illuminated display section is switched from the non-illuminated state to the illuminated state, the display content from the illuminated display mechanism on the surface of the sheet body having light transmittance is
The three-dimensional effect of the moire pattern is more clearly expressed while producing a smooth gradation effect.

Further, when the display contents from the illumination display mechanism are set to move in the horizontal direction, the synergistic effect of the moving image property of the display contents and the smooth gradation effect makes the moving image and the stereoscopic display contents. Can be expressed. (Embodiment 4) Next, Embodiment 4 will be described focusing on differences from Embodiment 2.
